                      Cold Heading:Wire is cut and cold formed into spherical blanks on high speed heading machines

                      Flashing removes the seam from the heading operation and brings balls to the approximate size and sphericity required

                      Heat Treatment: The balls are heat treated (hardened and tempered) to achieve the required hardness and microstructure

                      Hard Grinding: The hardened balls are ground to the precise geometric size in the hard grinding operation

                      Lapping: The finish lapping operation gives the balls the bright, smooth, defect-free surface finish

                      Roller Sorting: Roller gauges detect and sort out surface defects, under/oversize balls
